Abstract
Polarization rotation or selection appears in materials with optical activity, or those with Faraday
effect, or in liquid crystals. In this letter we present a structure, with an analogous response, using
stacked extraordinary transmission subwavelength hole arrays modified to be nearly
self-complementary. This produces a polarization selector because of the negative index of

Polarization rotation or selection appears in materials with optical activity, or those with Faraday
effect, or in liquid crystals. In this letter we present a structure, with an analogous response, using
stacked extraordinary transmission subwavelength hole arrays modified to be nearly
self-complementary. This produces a polarization selector because of the negative index of
refraction for one of its linearly polarized eigenwaves. Simulation results and experiments at
millimeter wavelengths confirm these features. Applications in miniaturized devices are envisioned
as well as the possibility to scale to optical wavelengths. [--]
